Virtual Sensor for Liquid Raw Material Monitoring

The patent creates a virtual sensor that copies the detection function of the physical liquid level detector. The virtual sensor calculates liquid level position based on remaining amount data from the storage tank, providing continuous detection coverage without requiring additional physical sensors at every possible detection position. This resolves the contradiction by adding computational capability rather than physical detection infrastructure.

The patent introduces an intermediary calculation system that bridges the gap between the physical liquid level detector and the required continuous monitoring. The remaining amount data serves as an intermediary that enables precise calculation of liquid level position even when the physical detector cannot directly measure the level, thus improving measurement precision without proportionally increasing device complexity.

The patent implements a feedback mechanism where the virtual sensor continuously calculates and provides liquid level information based on remaining amount data. This feedback loop ensures that even if the physical detector fails, the system maintains reliable monitoring through the virtual sensor's continuous calculations, thereby improving reliability without requiring a completely redundant physical sensor system.

The patent changes the parameter from direct physical detection to calculated parameter derivation. Instead of relying solely on physical sensor readings, the system uses remaining amount data to calculate liquid level position, transforming the monitoring approach from binary sensor states to continuous calculated values. This parameter transformation enhances reliability by providing continuous monitoring capability independent of physical sensor limitations.
